Description

BQ2004PN Overview
This can be found in the Tube package.We've included it in the 16-DIP (0.300, 7.62mm) package so that it's easier to use.The mounting type of the device is Through Hole.It is recommended to set the temperature to -20°C~70°C TA for reliable performance.A analog IC of POWER SUPPLY SUPPORT CIRCUIT has been used in the design of this device.To charge the device, Constant Pulsed current is required.Identify its related parts based on the base part number BQ2004.As a whole, it contains 16 terminations.There are 16 pins on it.There are various programmable features, such as Voltage.In order for it to work, it requires 16 pins.A total of 1 channels are available.It can be powered by a battery with 5V.As long as the supply voltage is 5.5V, it is capable of withstanding the voltage.It is in this instance that the device's output current is set to 2A.A power supply voltage as low as 4.5V can be used for it and it will work as well as possible.There is a minimum input voltage of 4.5V volts.As a rule of thumb, the supply voltage needs to be set to 5V for optimum efficiency.As far as switching frequency is concerned, the part runs at 300kHz.

The bq2004 Fast Charge IC pro-vides comprehensive fast charge control functions together with high-speed switching power control circuitry on a monolithic CMOS device. Integration of closed-loop current control circuitry allows the bq2004 to be the basis of a cost-effective so-lution for stand-alone and system integrated chargers for batteries ofone or more cells. Switch-activated discharge-before-charge allows bq2004-based chargers to support battery conditioning and capacity determination. High-efficiency power conversion is accomplished using the bq2004 as a hysteretic PWM controller for switch-mode regulation of the charging current. The bq2004 may alterna-tively be used to gate an externally regulated charging current. Fast charge may begin on applica-tion of the charging supply, replacement of the battery, or switch de-pression. For safety, fast charge is inhibited unless/until the battery temperature and voltage are within configured limits. Temperature, voltage, and time are monitored throughout fast charge. Fast charge is terminated by any of the following: Delta Rate of temperature time(Delta T/Delta t) Delta Peak voltage detection (PVD) Delta Negative delta voltage (-Delta V) Delta Maximum voltage Delta Maximum temperature Delta Maximum time After fast charge, optional top-offand pulsed current maintenance phases are available.
